Overview

A breakout pcb that helps make pedal wiring less nightmarish. Intended to be used with these: https://github.com/christrotter/microswitch-pcb

I needed a cleaner way of wiring up my pedals, and now that I know how to make basic pcbs...well, for the price, hard to go back to janky prototyping boards.

Don't mind the renders, it's meant to utilize JST-XH horizontal connectors pointed inwards to minimize the room needed for cable routing space.

• This is meant to be super simple - just a breakout pcb
• TRRS PB-320A footprint wired up for full-duplex serial
• JST-XH 8-pin for your external indicator module
  • 2x buttons
  • LED in
  • +5V/GND
  • Reset
• 3x JST-XH 6-pin for MCU row/col, led, power/gnd, reset, serial, etc
• 1x 2-pin for reset
• 8x JST-XH 6-pin for button PCB connectivity
  • +5V/GND
  • LED IN/OUT
  • ROW & COL
• 8x JST-XH 4-pin for any internal LED necessities
  • +5V/GND
  • LED IN/OUT

I was going to do the whole nine yards and put in serial power protection and data esd, led signal up-convert, and more...but PCBA + shipping would end up being $60-80. This design ended up being $19 shipped (then an $8 coupon brought it down to $11 shipped).
